3D: Getting to Know the Basics

By Stephen Hopkins
Here is the first of our weekly series covering the burgeoning 3D technology, beginning with the basics.


You've no doubt heard is taking over the video landscape this year.


Along with the daily coverage of product introductions and news regarding 3D, we will be providing informational and other elements about 3D every week on ElectronicHouse.com.


We're going to start with a basic introduction of how 3D works, some basics about equipment, and a few history tidbits.



What is 3D?

3D Imaging, classically known as Stereoscopy, is any technique capable of recording three-dimensional visual information or creating the illusion of depth in an image. Stereoscopy dates back nearly as far as photography itself and derives its name from the Stereoscope.

How is the 3D effect created?

The visual effect of depth in an image (static or moving) is created using Stereopsis (from stereo meaning solid, and opsis meaning sight). Two slightly different images are projected on to each retina, and, due to the different locations of each eye in the head, the brain resolves the binocular disparities in the image to generate the perception of depth.
